A detachment and retrieval mechanism for a central venous access filter includes a catheter body, and an outer sheath concentrically disposed about the catheter body. The outer sheath and the catheter body are moveable relative to one another. A filter member includes a first end coupled to the catheter body and a second end movable relative to the catheter body. The first end comprises a collar that is immovably coupled to the catheter body in a first state and movably coupled to the catheter body upon transition to a second state. |
